1MPROV EMENTIN APPARATUS FOR STEAMING VEGETABLES, 80c.

Specification forming part of LettersPatent No. 2,033, dated April 2,1841.

To all whom it may concern:

Be it known that we, ASA MUNGER and JAMES S. MARSH, of Auburn,count-yofCa-yuga, and State of New York, have invented a new and usefulimprovement in an apparatus for heating water and for steamingvegetables and performing other culinary operations and other purposesfor which steam may be Wanted; and we do hereby declare that thefollowing is a clear and exact description of the construction andoperation of the same, reference being had to the annexed drawings,making part of this specification.

Figure 1 is a perspective view. vertical section.

Similar letters refer to similar parts in the figures.

Fig. 2 is a The boiler 13 of said apparatus for heating.

the water should be about two feet long by nine and a half inches indiameter from outside to outside, made double, and composed of copperfor the inside B and zinc for the outside cylinder B or any other metalmay be used. The cylinders are placed threefonrths of an inch apart, andmade perfectly tight for holding water. Both ends of the inside cylinderare open, with a grate G at the bottom and stove-pipe 1 on the top,furnished with a damper D, to command and control theheat. The dampershould be placed in the stove-pipe near the top of the boiler. A plateor door'on each side of the boiler should be arranged, which may beremoved for the purpose of cleansing the inside of the boiler, and alsoa faucet F for drawing the water from the boiler.

Thetub T for containing water is made about twenty inches high andtwenty inches in diameter at the top, tapering to seventeen and one-halfinches at the bottom, and may be made of wood or metal, or it may bemade of any required shape and of suitable material.

The frame A for containing and supporting the boiler and tub may beabout four feet long and nine and one-half inches wide, standing; onfour legs twenty-two inches high, and made of two-inch stuff. (The widthof the frame is calculated from inside toinside, so as to admit theboiler.)

The connecting-tubes e c should be made of copper, zinc, or other metal,two inches in diameter, and connect the tub and boiler, as follows: Thetub T is placed on the top of the frame. Theboiler ll is placed withinthe frame, and the top of the boiler stands four inches above the bottomof the tub and about six inches from it. The upper tube a fordischarging the heated water and steam from the boiler into the tub isstraight, running horizontally from the side and near the topoftheboiler into the tub' one inch from the bottom 'of-thetub, andrunning to the center of the tub inside. The lower tube 0 for sup plyingthe boiler with water from the tub is put through the bottom of the tubthree inches from the side anddirectly under the upper tube, and abridge E of metal is placed over both tubes (in the tub) to protect themfrom injury. The lower tube has an elbow and enters the boilerabout fouror more inches from the bottom. From the inside of the boiler anddirectly opposite the place where the lower tube enters the outsidecylinder (of the boiler) a worm'Vt oru'hollow tube of copper one or moreinches in diam-.

eter is placed and secured to the inside cylinder, (of the boiler,) andafter making two or three turns within the fire-chamber is carried tonear the top and enters the inside'cylinder directly opposite the uppertube c,dis-

charging the steam and heated water into the boiler and thence into thetub, the space between the inside cylinder or fire-chamber and tube orworm to, be half an inch. The water passes from the boiler or spacebetween the two cylinders into the worm, which is keptv constantlyfilled and circulating therein, the upper end of said worm also openinginto boiler at top. The steam is taken from the head of the tub T, whichis secured with hasps and keys, and carried by-a steam-pipe H to anyobject for which it may he wanted, such as a vessel V, in which articlesmaybe cooked. The whole apparatus may be enlarged or diminished to anysize by following' the proportions as given above.

We do not claim to be the inventors of the worm in the fire-chamber, norof the combination of the tub and boiler without the worm; but

What we do claim as our invention, and desire to secure by LettersPatent, is

The combination of the worm in the firechamber with the boiler and tub,for the purpose and in the manner set forth and specified above.
